Credit Check Summary
The objective is to provide Distributors with an API endpoint for conducting standard customer credit checks. If the credit check fails, the sale cannot proceed.
This step enables the Solution Provider (SP) to verify the end-customer’s eligibility for credit approval. Credit Check approvals are critical prerequisites before proceeding further. After the process of quote ID validation and Address Validation of Postal Service (AVPS) validation, the actual credit check is performed.

Security
This RESTful service uses a client id enforcement policy as the authentication mechanism. Please work with the Client On-Boarding Team if you do not have the necessary credentials.
